virus/spyware trouble, i just got this laptop too... Options

[Haruka]

ok so here's the thing, my laptop is realling getting on my nerves.

I open IE (internet explorer) and my home page is automatically turned into a search page, i get an error message about how run.dll doesn't work and my norton antivirus is detecting all my temp internet files as viruses and everytime i push "ok" another one pops up and even if i stay here all day turbo clicking, it won't go away. o, and everything is running REALLY SLOW.

to see what i mean, i took a screen shot of it:

these are the following antiviruses/antispyware i have installed:
Norton 2005
Bitdefender
Ad Aware SE
Spybot Search and destroy
Mc Afee

I have run each and everyone of these all day and for some reason they detect things, i delete them, then run the search again and THERE IT IS AGAIN! Something is copying this virus/spyware and cannot be detected.

any suggestions? i'm THISCLOSE TO throwing this piece of junk out the window. Thanks in advance.
